Summary: Square-shaped monolithic B4C and B4C-ZrB2 composites were produced using SPS method. The addition of 5, 10, 15 vol% ZrB2 had an effect on the densification, mechanical and microstructural properties of boron carbide. The density of B4C increased with increasing volume fraction of ZrB2 and the density differences in different regions of the sample decreased. The addition of ZrB2 enhanced the hardness and fracture toughness of the composites compared to monolithic B4C. The B4C-15 vol% ZrB2 composite exhibited superior properties with a hardness of 33.08 GPa and Vickers indentation fracture toughness of 3.82 MPa·m1/2.

Summary: Ultra-high temperature ceramics (UHTCs) are of interest due to their high melting temperatures and ablation resistance, but their widespread use is limited by low fracture toughness and processing challenges. This study introduces fiber-reinforced UHTC matrix composites (UHTCMCs) produced via direct ink writing (DIW), with up to 47.5 vol% of ZrB2 and up to 10 vol% of SiCf. The research demonstrates the successful fabrication of UHTCMCs with aligned fiber reinforcement and discusses defects occurring during the DIW process.

Summary: The wetting and infiltration behavior of molten ZrSi2 alloys into C-f/SiC and B4C-infiltrated C-f/SiC composites are affected by Si evaporation and overall porosity. Composites with lower porosity show better wetting and spreading of the alloy on the surface, while composites with higher porosity exhibit the formation of an outer dense layer followed by a uniform infiltrated region. Lu2O3 particles are not wetted by the melt and are pushed away by the solidification front during the reaction process.

Summary: SiC-TiC-diamond composites were fabricated via spark plasma sintering, and the behavior of composite densification was analyzed. The decomposition of diamond into carbon and the reactions with Si and Ti to form SiC and TiC were observed. The composite density decreased with the increase of hold temperature for uncoated diamond composites, while the porosity fraction increased for TiC-coated diamond composites.

Summary: This study investigated the microstructural and mechanical properties of (ZrxTi1-x)N-(TixZr1-x)B-2 composite fabricated by reactive spark plasma sintering (SPS) of ZrB2 and TiN. It was found that high Vickers microhardness, flexural strength, and fracture toughness were achieved for this composite, with dominant toughening mechanisms being the fracture of the (ZrxTi1-x)N and (TixZr1-x)B-2 phases and crack path deflection.

Summary: The study employed spark plasma sintering to join two pre-sintered HfB2-ZrB2 and HfB2-ZrB2-SiC composites using Ni powders as an interlayer. Solid-state diffusion of Ni into UHTCs resulted in the formation of continuous and crack-free interfaces. While the HZ/Ni/HZ joint exhibited reduced hardness due to microstructural inhomogeneity, the HZS/Ni/HZS joint achieved uniform hardness owing to microstructural homogeneity.

Summary: In this study, B4C-SiC-rGO composites with varying SiC contents were prepared and their microstructures and mechanical properties were investigated. The results showed that the addition of 15 wt.% SiC to 5 wt.%-GO reinforced B4C composites resulted in the optimal values for flexural strength and fracture toughness. The presence of SiC and rGO not only inhibited the growth of B4C grains, but also improved the mechanical properties of the composites.

Summary: This study investigated the joining of Cf/SiC and Si3N4 using glass and identified direct bonding as the main interfacial bonding mechanism. The joint showed a maximum shear strength of -34 MPa and remained at -13 MPa after thermal shock for 10 cycles. Bubbles in the glass filler were found to be the main factor causing degradation of joint performance. Improving the high temperature resistance of joining materials is suggested for application of this joint structure.

Summary: The study examined the use of elevated temperature to expedite nickel release testing in nitinol medical devices. It found specific behavior patterns in nickel release in materials with relatively thin oxide layers, allowing for shortened testing duration at higher temperatures. Materials with thicker oxide layers showed release behavior that did not follow a specific pattern. Further testing and insights are needed for establishing a protective temperature scaling for all nitinol medical device components.

Summary: In this study, CBS glass/Al2O3 composites were developed for LTCC applications based on a CaO-B2O3-SiO2 (CBS) glass system with a high boron content. The study revealed that the softening of glass and interfacial reaction between the glass and Al2O3 were the two most important factors affecting LTCC's densification process. Real-time shrinkage rate of LTCC during sintering was successfully simulated, and it was proven that the formation of the CaAl2(BO3)O phase played a significant role in reducing glass viscosity and promoting dense structure formation. The resulting LTCC composite exhibited excellent performance for high-frequency applications.

Summary: In this study, the disordering caused by swift heavy ion irradiation in two different compositions of pyrochlore structures was investigated. X-ray diffraction, Raman spectroscopy, and high-resolution transmission electron microscopy were used to analyze the samples before and after irradiation. It was found that both compositions underwent amorphization due to irradiation, with a slower rate observed in Nd1.8Zr2.2O7.1. The irradiation-induced modified track region in Nd1.8Zr2.2O7.1 consisted of defect-rich pyrochlore structure, anion-deficient fluorite structure, and amorphous domains.

Summary: Silicide ceramics, including tantalum disilicide (TaSi2), are known for their exceptional physical properties but are limited in practical applications due to their inherent brittleness at room temperature. In this study, we successfully improved the mechanical properties of TaSi2 ceramics and increased their electrical conductivity by modifying the preparation methods and sintering conditions. These findings provide valuable insights for future applications of TaSi2 and the design of advanced ceramic materials.

Summary: Microstructure design plays a crucial role in regulating the microwave dielectric properties of materials, however, the understanding of frequency temperature stability and related micromechanism remains limited. In this study, a combination of first-principles calculations and experimental observation was used to investigate the correlation among sintering behavior, crystal structure, bonding nature, and microwave dielectric properties of LnPO(4) (Ln = Eu, Pr) ceramics. The research findings systematically clarify the optimized effect and micromechanism of lanthanides on the dielectric properties of monazite ceramics, providing insights into the design and enhancement of microwave dielectric materials.

Summary: The study investigates the frictional and wear behaviors of carbon fiber-reinforced SiC ceramic matrix composites with different fiber orientations mating with ceramic balls. The results show that fiber orientation significantly affects the friction and wear properties of the composites. Pads with randomly arranged fibers demonstrate better friction stability and lower wear volume, potentially suitable for bearing material applications. The research also explores the factors influencing the formation of continuous tribo-film and identifies abrasive wear and oxidation wear as the dominant wear mechanisms for the friction pairs.

Summary: This study reveals the significant influence of resting time on the rheological properties of cement suspensions, which is closely related to non-absorbed polycarboxylate superplasticizers (PCEs) size variation. Adsorbed PCE during resting tends to bridge particles instead of dispersing them, leading to an increased yield stress.

Summary: This study investigates the effect of K/Na ratio on the phase structure, ferroelectric domains, and piezoelectric properties of potassium sodium niobate (KNN)-based ceramics. It reveals that high Na+ content leads to large ferroelectric domains, while high K+ content results in local polarity heterogeneity and distinct dielectric relaxational behavior. The balanced local polarity and stress heterogeneities contribute to improved piezoelectricity.

Summary: In this study, the micro-geometry morphology variation and microstructural transformation mechanism of muscovite crystals under electron beam irradiation were explored. The results revealed the instability of the muscovite lattice under irradiation, as well as the expansion and shrinkage of the lattice with increasing dose. The study also identified changes in chemical structure and other mechanisms involved. These findings are significant for the design of radiation-resistant silicate materials and the manufacturing of electronic components used in the aerospace industry.
